Carnage on the big screen can be traumatic, not to mention homicidal. And we’re not talking about movies for adult audiences.

British researchers have concluded that when it comes to death and murder, children’s films are worse than the entertainment their parents enjoy.

“Exposure to on-screen death and violence can be frightening to young children and can have intense and long-lasting effects,” the study published in BMJ states. “This might be particularly problematic when children have not been prepared, through candid discussion with parents or caring adults, to face these themes.”

The researchers added that “on-screen deaths can be particularly traumatic for children as they directly expose them to loss of life. Death, often gruesome and sensationalized, is featured prominently in North American films.”

Study leaders James Kirkbride, professor of psychiatry at the University College London, and Dr. Ian Colman, professor of psychology at the University of Ottawa, said: “Rather than being innocuous and gentler alternatives to typical horror or drama films, children’s animated films are, in fact, hotbeds of murder and mayhem,” and “rife with death and destruction.”

Death for main characters in kids’ films were more than twice as likely to happen, and three times more likely in the form of murder.
